Steven Jackson was limited in practice Thursday for the St. Louis Rams as he rested a tender knee. "My knee is good," Jackson said following Thursday?s practice. "It was a little swollen after the game Sunday (in Oakland). It took a whack early in the second quarter. So we?re just nurturing it, nothing serious. But Coach (Steve Spagnuolo) is allowing me time to allow it to heal, and that?s why I?ve been limited these last two days. But nothing to worry about."
